Dengie (Mid-Essex Coast Phase 1)

image: SPA location map 

 

Dengie is located on the coast of Essex in eastern England. It is a large and remote area of tidal mud-flats and saltmarshes at the eastern end of the Dengie peninsula, between the adjacent Blackwater and Crouch Estuaries. The saltmarsh is the largest continuous example of its type in Essex. Foreshore, saltmarsh and beaches support an outstanding assemblage of rare coastal flora. It is of importance for wintering populations of Hen Harrier Circus cyaneus, wildfowl and waders.

Dengie is an integral component of the phased Mid-Essex Coast SPA.
